Thread-pulling knife position
The thread-pulling knife (1) cannot be moved on the knife carrier (3).
Therefore, you will not have to adjust the cutting pressure after replacing
the thread-cutting knife (1).
The knife carrier (3) can be installed in 2 different positions: Large hook
and XXL hook. To do this, the knife carrier (3) is rotated by 180°.
In rest position, the thread-pulling knife (1) completely covers the cutting
edge of the counter blade (2). This prevents the needle thread from being
damaged.
The pivot range of the thread-pulling knife is 23°.
Fig. 62: General information (2)

tion situation.
